Gutter brightening is the cleaning of the outside face of your gutters to remove tiger stripes, oxidation, and dark streaks. Clearing the trough does not touch those marks. Fast Pro washes the face of each run with a gutter-safe cleaner and a low-pressure rinse, so the gutters match the rest of your roofline.

Gutter brightening in Miami, FL
Sun, humid air and salt near the bay dull painted gutters, and runoff from a streaked roof leaves dark stripes on the gutter face. We test a hidden spot first, then wash the face of each run with a gutter-safe cleaner.
Painted aluminum gutters oxidize in strong sun. The surface turns chalky, and the chalk grabs whatever the roof sends down: dust, pollen, algae spores. The stripes you see are that mix, dried in vertical lines. A hose will not move them, and a pressure washer risks scarring the paint.
The stripes are usually worse under a roof that is itself streaked. Tile and flat roofs grow algae and mildew in Miami's humidity, and every storm washes some of it down the gutter face. That is why brightening lasts longer when the roof is washed in the same visit.
Near Biscayne Bay and the ocean, salt in the air adds wear to the finish. We test a hidden spot before we start, because the same cleaner behaves differently on sound paint and on paint that has chalked or started to flake. If the finish is worn through, we tell you what the gutter can and cannot recover before we do the whole house.
Brightening cleans the outside only. We clear the inside of the gutter first, so the rinse water leaves through a clear trough, and we point out rust, which no cleaner removes.
If you plan a roof wash, book the brightening for the same day. Washing the roof first keeps fresh runoff off a gutter face you have just cleaned.
A west-facing gutter that catches Miami's afternoon sun most of the year usually chalks and streaks before one on the shaded side of the same house, which is why two runs on one roof rarely need brightening on the same schedule.
What tiger stripes are and why gutters get them
Tiger stripes look like dirt. They behave like a stain, because they are bonded to the finish.
Painted aluminum gutters slowly oxidize in the sun, which leaves a thin chalky layer on the surface. Rain running off the roof carries dust, pollen, and particles from the roofing. That mix sticks to the chalky layer and dries into vertical streaks. A garden hose will not shift them, and neither will a pressure washer, because the problem sits in the surface and not on top of it.
| Mark | Looks like | Usually caused by | What we do |
|---|---|---|---|
| Tiger stripes | Black or gray vertical streaks | Oxidized finish holding roof runoff and pollen | Apply cleaner, work it in, rinse at low pressure |
| Chalky oxidation | White or gray powder that rubs off on your hand | Sun and age breaking down the paint surface | Clean and brighten, then check the finish underneath |
| Mildew and algae spots | Green or black dots on shaded sections | Damp, shaded gutter faces under trees | Treat and rinse the affected sections |
| Overflow stains | Brown streaks below a clogged downspout or corner | Water spilling over a blocked gutter | Wash off, then fix the cause with a gutter cleaning |
| Rust | Orange or brown spots at seams and fasteners | The metal breaking down | Not removable by brightening, we flag it for repair |
Gutter cleaning or gutter brightening?
One handles what is inside the gutter, and the other handles what shows on the outside.
| Gutter cleaning | Gutter brightening | |
|---|---|---|
| Works on | The inside of the trough | The outside face |
| Removes | Debris, pollen paste, grit | Tiger stripes, oxidation, surface stains |
| Helps with | Water flow and overflow | How the house looks from the street |
| Done | Two to four times a year | When streaks show, often with a cleaning |
Start with the gutter cleaning if the trough has not been done this year.
What makes gutter finishes streak faster
Several things work against a gutter finish, and they stack.
- Sun
- Strong UV breaks down paint on aluminum, which gives streaks a surface to grab.
- Humidity and shade
- Damp shade under trees and eaves grows mildew on the gutter face.
- Pollen and runoff
- Pollen and roofing particles ride the rain down the face of the gutter.
- A streaked roof
- Algae on the roof washes down and stains the gutter below it.
If your roof has dark streaks, the gutters under it will keep streaking until the roof is cleaned. See our roof pressure washing page.
How we brighten gutters
We work in sections so the cleaner never dries on the finish.
- 1
We clear the trough first
Debris comes out by hand before any cleaner goes on. A full trough sends dirty water down the face of the gutter and undoes the work.
- 2
We protect the plants
Shrubs and flower beds under the gutter line get wet down and covered.
- 3
We test a hidden spot
A small patch on a low, out-of-sight section tells us how the finish reacts, and whether the paint is sound, before we do the rest.
- 4
We apply the cleaner to the face
The cleaner goes on one section at a time and sits just long enough to release the streaks.
- 5
We work it where it needs it
Stubborn tiger stripes get a soft brush or pad. We do not scrub hard on the finish, because that scratches it.
- 6
We rinse at low pressure
The face and the underside of the gutter get a gentle rinse, then the plants and the ground below.
- 7
We photograph the result
You get before and after photos of each run, and a plain note on any section that would not fully clean.
Heavily oxidized gutters may brighten but not return to like-new. The test spot tells us first.
Before and after: a gutter face brightened

Gutter brightening questions, answered
How much does gutter cleaning cost in Miami?
The price depends on the feet of gutter, the number of stories, how packed the runs are and whether guards are installed. Many Miami homes have only short gutter runs over entries and garages, which keeps the job smaller. Call with your ZIP code and we quote by phone.
How much does roof cleaning cost in Miami?
It depends on the roof size, the material, the pitch and how much algae is on it. A one-story tile roof and a two-story flat roof are different jobs. Tell us the roof type and the stories and we quote by phone.
When is the best time to clean gutters in Miami?
Early May matters most, before the wet season starts on May 15. A second visit between mid-October and December clears the debris left by hurricane season.
How often should a Miami tile roof be cleaned?
Every two to three years suits most roofs. Shaded slopes and roofs under trees grow algae sooner.
Do you clean gutters and roofs after a hurricane or tropical storm?
Yes. Storms leave fronds, branches and shredded leaves on the roof and in the trough. After a named storm we move cleanups to the front of the schedule and flush every downspout.
Does my Miami home need gutters?
Not always. Many Miami homes shed water from the roof edge. If you have gutters or downspouts, we clean them. If you do not, a roof wash and a check of the drains and the ground along the drip line still protect the house.
Is it safe to pressure wash a tile roof in Miami?
Pressure is the risk. Tile makers' care guides cap cleaning pressure at about 1,200 psi and warn that some cleaners can etch concrete. We use a soft wash and a concrete-compatible cleaner, and we step only where tiles overlap.
Why do my gutters streak faster under a tile roof?
Algae and mildew on the roof wash down the gutter face with every rain. Cleaning the roof and the gutter face together keeps the result longer.
Will brightening work on gutters faded by the sun?
It removes dirt and streaks. If the paint itself has chalked or worn through, the test spot shows what is possible.
Should I wash the roof before brightening the gutters?
Yes. Wash the roof first, then brighten the gutter face, so fresh runoff does not bring the stripes back right away.
Gutters streaked from top to bottom?
Call and tell us what the gutters look like and what they are made of. We quote by phone and find a day that works.
